Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To enable to weld effectively without greatly spoiling the appearance of the periphery of the welding surface in a manufacturing apparatus for a on-vehicle lamp for welding a front lens and a lamp body through hot plate welding. SOLUTION: When hot plat welding for the front lens 16 and the lamp body 14 is performed, both planned welding surfaces 16b, 14b are heated by being arranged in the proximity of a lens heating surface 116b of a heating element 116 and a body-heating surface 114b for a specified time. This enables to prevent transforming of the place near both planned welding surfaces 16b, 14b and the generation of foam burr on the both sides. Also a ceramic film is formed on the lens heating surface 116b and the body heating surface 114b. Thus thermal energy in the infrared wavelength region which is easily absorbed into the front lens 16 and the lamp body 14, is irradiated secondarily towards the planned welding surfaces 16b, 14b and the heating time is to be shortened.
